To all whom it may concern.-

chines, (Case 7,) of which the following is a full, clear, concise, and exact description,

' reference being had to the accompanying drawings, forming apart of this specification. 7

My invention relates to calculating machines and in general may be regarded as an automatic multiplying device.

While some features of my invention may be employed in purely abstract multiplications or calculations, it is particularly useful in multiplications involving mixed num-- bers and, translations of value from one scale to another.

.One of the utilities of my present invention is the translation from pounds sterling of the English monetary system into United States dollars and cents, or vice versa. In constructing a machine for this purpose, I provide a register comprising a series of numeral wheels, one of each order in combi nation with carryingmechanism corresponding with the scale involved in one or the other system of values. This register is connected with an actuating mechanism in a ratio of gearing corresponding with the relative value of a unit'in one system as compared with that of a unit in the other system. One operation of the actuating mechanism therefore causes an actuation of the register to indicate the. value in unitsof one system, of one unit in the other system. Further operation of the, mechanism causes the register to indicate in units of its scale, the value of the total number of units in the other scale, for ,which actuations have been made. ,Not. onlyis there a single actuating mechanism corresponding with one denomie nation in the scale upon which the actuating mechanisms are arranged, but in the prefer'red form of my invention there is an actuating mechanism for each denomination in the scale. Each of these actuating mechanisms is geared to the register in a ratio corresponding with the value of a unit in the order to which it is assigned as expressed in units of the scale in accordance with which I CALCULATING-MACHINE.

Specification of Letters Patent. Patented Jan. 28; I913. Application filed January 1t, 1908. Serial No. 410,925.

the numeral wheels of the register carry. In the preferred form of my inventionthe actuating mechanisms 0- erate directly upon the numeral wheels 0 well as upon the numeral wheels of the lowest order, thuscsaving alarge amount of operation of the lower orders which would otherwise be required in order to carry into the higher orders.

When my invention is to be used inthe translation from pounds sterling to United States money e ulvalents, I rovide a register composed o numeral w eels associated with-suitable tens-carrying mechanism, conforming to the decimal scale of notation and from this register the amounts in dollars and cents are read. I provide also ,a set of.

higher orders as i ordered actuating mechanisms,""a s for example 21. pence actuating mechanism, a-shillings actuating mechanism, a units of ounds actuating mechanism, a tens of poun s actuating mechanism, etc. 1 Each of these actuating mechanisms includes a rotatable shaft upon which a number of actuating wheels are mounted. The manner of gearing the actuating wheels to the various numeral.

wheels of the register is such-that one complete operation of the actuating mechanism of any order will directly advance the dollars wheel, the dimes wheel, the cents wheel and the mills wheel by amounts whose total isequivalent to one unit of that order in the sterling scale. :3

In order that the numeral wheels shall be free to be actuated by the carrying mechanisms as well as directly by the actuating mechanisms, I have devised a simple means for causing the actuating mechanisms directly to actuate the numeral wheels one at a time. This leaves all of .the other numeral wheels free to bev actuated by the carrying Figure 1 is a front elevation of the translating or calculating machine, the cover being removed in order to reveal more'clearly the interior mechanism. Fig.- 2 is an ,end elevation of the major part of the machine.

Fig. 3 is a cross sectional view taken on the line 33 of Fig. 1, as indicated by heavy arrows. Fig. 4 IS a cross sectional view taken on line 4-4 of Fig. 1, as indicated by the heavy arrows. Figs. 5, 6, 7, 8, 9 and 10 are artial cross sectional views taken on the lines indicated by the arrows 5 to l0, inclusive of Fig.1, these views being diagrammatic illustrations of portions of the gearing involved. Fig. 11 is a detailed view of one of the carrying disks and the associated intermittent carryin wheel. Fig. 12 is an enlarged view of t e parts shown in the upper right-hand corner of Fig. 3, and Fig. 13 is an enlarged "iew of the parts shown in the upper right-hand corner of Fig. 4.

In the first place my invention involves a register composed of numeral wheels and the associated carryin mechanisms. This register as illustrated in the drawings comprises the numeral wheels T, M, C, D, O and E, these numeral wheels being assigned respectively to the indication of tenths of mills, mills, cents, dimes, single dollars, and tens of dollars. Manifest-1y the number of numeral wheels may be carried up to provide for an desired order. All of these numeral whee s are loosely mounted upon a resetting spindle 20. Each of the numeral wheels is attached to an associated locating wheel 21, and to a driving gear 22, and also to a carrying-disk 23, which is provided with two suitable carrying teeth 2424, the numerals which designate the parts associated with each numeral wheel being supplied with indices t, m, c, d, 0 or e, as the case may be. T The function of the locating wheel is to cooperate with an associated locating detent 25, 25", etc, these detents serving to bring the numeral wheels into exact position for reading through the window W.

Each carrying mechanism comprises an intermittent carrying wheel actuated by the teeth of the carrying disk, the intermittent carrying wheel being attached through ratchet mechanism to a carrying pinion which is in mesh with the driving gear of the numeral wheel of the next higher order. It is through the operation of these parts that the numeral wheel of a given order is advanced through one space whenever the numeral wheel of the next lower order has been turned through an angle corresponding with the number of units which make up one unit of the higher order in the scale involved. Thus, for example, the intermittent carrying wheel 26 is loosely mounted upon the actuating shaft 53 and is adapted to be actuated twice during each revolution of the numeral wheel T by one of thejcarrying teeth 24. The contour of the intermittent carrying wheel and its relation to the carryin disk and carrying teeth are indicated in Fig. 11. It will be seen that the edge of the carrying disk projects within with the teeth of a ratchet wheel 29. l hen,

therefore, the numeral wheel rotating in the direction indicated by the arrow 30 in Fig. 3, moves through the zero position one of the carrying teeth 24 of the associated carrying disk will engage a notch in the periphery of the associated intermittent carrying wheel, causing a one-tenth rotation of the carrying wheel in the direction of the arrow 31. Rotation of the carrying wheel in this direction will cause the pawl 28 to engage a tooth of the ratchet wheel 29 to cause a one-tenth revolution of the ratchet wheel in the direction of the arrow 31. The ratchet wheel is formed on a sleeve which is integral with an associated carrying pinion 32. In the ease of all of the numeral wheels,

except that of the lowest order, there is attached to the numeral wheel a carrying gear 33 in mesh with the carrying pinion which carries up from the next lower order. The result is ;that whenever the numeral wheel of a lower order is turned through the zero position the carrying gear train will be rotated to cause a one space rotation of the numeral wheel of the next higher order. The reason for the ratchet connection between the intermittent carrying wheel and the carrying pinion will subsequently appear. Each of the numeral wheels as shown in the drawings is provided with two sets of digits from zero to nine inclusive, and it is for this reason that the carrying disks are each provided with two carrying teeth. This particular number of carrying teeth and sets of digits for each numeral wheel is selected on account of'the convenient size which it enables the designer to adopt in laying'out the gearing.

It will be apparent that any amount in dollars and decimals of dollars may be set up by proper rotations of the numeral wheels of the register. Furthermore the ratchet device in the carrying mechanism will enable one to advance a numeral wheel of higher order without affecting the position or causing I'OttlLlOIl of a numeral wheel of lower order. Thus, for example, if one were to advance the tens of dollars numeral wheel a he would cause a rotation of the associated carrying pinion 32 in the direction of the arrow 31, as shown in Fig. 3. Such rotation of the carrying pinion would cause rotation in the same direction 'of the ratchet wheel 29. Such rotation of the ratchet wheel, however, would not cause a corresponding movement of the associated intermittent carrying wheel 26 because the pawl 28 would slip over the ratchet. teeth. It will be apparent, therefore, that any numeral wheel may be advanced; without efiecting a rota tion.of the numeral wheels of lower order, but advancement ofrany numeral wheel will cause proper carrying into the numeral wheels of higher order, whenever the. numeral wheel of. lower order is' advanced through the zeropo'sition.

The value of one pound sterling in English money is 4.8665 dollars, as expressed in United States money. In order,therefore, to cause the" numeral wheels of the register toindicate in dollars-the value of pound sterling, it would be-neces'sary to Vance the units of dollars numeral wheelrO fromfits zero position to the posi-.

tioif'inwhi-ch the numerals would appear behind the window W, to advance the dimes wheel D to theeighth position, the cents wheel to the sixth position, the mills wheel to its sixth position, and the tenths of mills wheel to its fifth position, all as indicated in Fig. 1 of the drawing. My invention provides an actuating shaft equipped with actuating wheels for advahcing these nu meral wheels through the number of spaces above indicated "upon each actuation. order, therefore, to translate. one pound into United'States money equivalents, the units of pounds actuating shaft is turned through one complete revolution. If the numeral wheels of the register were in their zero positions prior to the commencement of th s revolution of u the actuating shaft, they will'indicate $48665 upon the com'- pletion of one such revolution of the actuating shaft. A second revolution of the actuating shaft will cause a similar advancement of thesenumerals wheels, causing a total of $91330 to appear through the window W. Additional revolutions of first. describe v.in detail the tens of pounds rious diagrammatic figures 5 to inclusive:

the units of ounds actuating mechanism will cause ad itional rotation of the numeral Wheels with corresponding indications of the totals expressed in dollars and decimal fractions thereof. Simil'ar actuating mechanisms are provided foradvancing the nushillings, pence, etc.

With this preliminaryexplanation I shall meral wheels by. amounts corresponding with actuating mechanism The tens of pounds actuating shaft is indicated at 35, this shaft being equipped;

at its exposed end with the operatingcrank 36. Since ten pounds are equal to-$48.665 as expressed inUnited Statesmoney, the.

of ounds' actuating'shaft is provided first wit an actuating wheel 37, this wheel being provided with four teeth i The vasliow the actuating gears in their normal position. It will be noted that thegear37' is in such a position that upon the commencement'. of a counter-clockwise rotation of the shaft 35, the four .gear teeth of the wheel 37 will immediately engagethe teeth of the .driving gear 22 of the tens of dollars numeral wheel E and cause its advancement through four spaces. The'second actuating gear 38 of the tens of pounds actuating mechanism is provided with eight teeth, as best illustrated in Fig. 6. These eight teeth are placed in an angular position upon the periphery of the wheel 38, such that they will not engage the teeth of the driving gear 22 of the units of dollars numeral wheel until after the teeth of the first actuating gear 37 have passed out of engagement with the teeth of the driving gear of the numeral wheelE. yThe continued rotation of the actuating shaft will, however, cause the eight teeth of the actuating gear-38 to ad-.

vance the unitsof dollars numeral wheel to its eighth position. The next actuating gear 39 of the tens of pounds actuating mechanism is provided with six teeth as best illustrated in Fig. 7. These teeth are placed in such an angular position u on the periphery of the wheel 39 that a ter 7 the teeth of the gear 38 have passed out of mesh with the teeth of the driving gear 22, the teeth of the gear 39 will mesh with the teeth of the driving gear 22 to -cause the advancement of the numeral wheel D through six spaces. In like mannerthe next actuating gear 40 of the tens of pounds actuating mechanism is provided with six teeth so placed as to engage the driving gear of the cents numeral wheel C and cause its advancement through sixspaoes United States money equivalents involves no change in the tenths of mills order, and,

therefore, the tens of pounds actuating shaft requires no actuating gear for advancing the tenths of mills numeral wheel. Fig. 10, therefore, shows the tens of pounds actuating shaft 35'to be without any actuating wheel in the tenths of mills position. It will be understood, of course, that these diagrammatic views shown in Figs. 5 to 10 inclusive, may be regarded as sectional slices of the mechanism. Whatever gear wheels or projecting teeth would appear behind the plane on which the next section is taken,

are not shown in these diagrammaticviews.

In view of the explanation previously made it will be apparent that a single rotation of the tens of pounds actuating shaft by means of the crank 36, will cause the fourspace advancement of the numeral wheel E,

the eight-space advancement of the numeral wheel 0, the six-space advancement of the numeral wheel D, the six-space advancement of the numeral wheel C, and the five-space advancement of the numeral wheel m, so that a single revolution will cause the indication of 8548.665. Subsequent revolutions of tens of pounds actuating shaft will cause a repeated advancement of the various numeral wheels to indicate the total value in dollars and cents of the number of tens of pounds which is to be translated. Itwill, of course, be ap arent that after a single actuation of tie tens of pounds mechanism, the units of dollars numeral wheel will be in its eighth position. The subsequent eight-space advancement of this numeral wheel will require the carrying ofone ten dollars into the tens of dollars numeral wheel. This will, of course, be accomplished by the carrying mechanism previously described. Such carryin will not be interfered with by the actuatlng wheel 37, because the teeth of this wheel will have passed out of mesh with the driving gear 22 before the second actuating wheel 38 begins to drive the numeral wheel 0, and, therefore, before any carrying will be required. In like manner all of the numeral wheels will carry into the numeral wheel of next higher order, whenever they pass through the zero position, and in no in-. stance will the actuating wheels or driving gears interfere with such carrving because the teeth of the actuating w eels always pass out of mesh with the associated driving gears before there is occasion to. carry up from a lower order.

The units of pounds actuating shaft is shown at 42 and, like the tens .of pounds actuating shaft, it is provided with a drive crank 43. The diagrammatic views of the actuating gears showthat this shaft is provided with no gear in the position occupied by the driving gear of the numeral wheel of highest order E. This is due, of course, to the factthat one pound is equivalent to only $48665, and the registration pound will not require any advancement of the tens of dollars numeral wheel. In the second position which is occupied by the drive gear of theunits of dollars numeral. wheel 0, ,the units of pounds actuating shaft 42 is provided with a four-toothed actuating gear 44. In the thirdposition, occupied by the driving gear of-the 'dimes numeral wheel D, the units of pounds actuating shaft is provided with an eighttoothed actuating gear 44. In the fourth position which is occupied by the driving gear of the cents numeral'wheel C, this actuof a single.

equivalent to $020277? ating shaft is provided with a six-toothed gear 45. In the next position which is 00- cupied by the driving gear of the mills numeral wheel M, the units of pounds actuating shaft is provided with a six-toothed wheel 46, and the last position, which is occupied by the tenths of mills numeral wheel T, the units of pounds actuating shaft is provided with a five-toothed actuating wheel 47. The en ar position of the teat on these various w eels is, as in the previous instance, .so arranged that the teeth of each wheel will as out of mesh with the associated driving gear before the teeth of the next succeeding wheel come into mesh, and M thus there is no interference with the immediate carr ing from any numeral wheel of lower order into a numeral wheel of higher order.

The shilling of the English monetary system is equivalent to $248325. While it would be ossible and perhaps feasible to provide additional numeral wheels to take account of this fraction to six places, I donot believe it is practically n to g0 beyond tenths of mills. In oonstructin my machine I have, therefore, disregard the last two significant fi res and have provided'an actuating mec anism to involve the register with $2433 for each rotation of the shillings actuating mechanism. The shil= lings actuating shaft is shown at 48, but for obvious reasons is provided with no actuating wheel in either the first or second ition. In the third position, indica in Fig. 7, the shillings s hit is provided with the actuating wheel 49, this wheel being provided with two teeth adapted for en-' gagement with the teeth of the drivin gear of the dimes numeral wheel D. n. thefourth position the shillings actuating shaft 48 is provided with a four-toothed actuat ing wheel 50 and-in the fifth and sixth positions the shillings shaft is provided with three-toothed actuating wheels 51 and 52, these wheels being adapted for en ent with the proper driving gears o t e numeral wheels of the register. Each complete revolution of the shillings actuatin shaft will cause, therefore, a two-space ed vancement of the dimes numeral wheel D, a four-s ace advancement of the cents numeralw eel C, a three-space advancement of the mills numeral wheel M, and a threespace advancement of the tenths of mills numeral wheel T. g

The pence actuating shaft is indicated at 53. Since one penny in the-English systemis I have arranged my mechanism to render this translation as .0203, which is the nearest four place value that can be assigned, and this value Iregard as a sufliciently close approximation for all practical purposes. For obvious reasons no actuating wheel is required in either the 1 first, s cond or third position, but in the with a two-toothed actuating wheel 54. In.

the mills position the pence shaft is pro-- vided with no actuating wheel, but in the tenths of mills position it is provided with a three-toothed actuating wheel 55. Each complete revolution of the pence actuating shaft will, therefore, cause a two-space advancement of the cents wheel, no advancement of the 'mills numeralfiwheel, but a three-space advancement of the tenths of 5 mills numeral wheel.

Since allof the carrying wheels and pinions T and their associated ratchet mechanisms are loosely mounted upon their shaft, I have ifor convenience mounted these parts upon the pence actuating shaft. ,The pence actuating wheels are, of course, keyed to the pence actuating shaft, but the rotation of the pence actuating shaft does not aifect the carrying wheels or pinions; neither does the pence actuating shaft. The shillings actuating shaft and the pence actuating shaft are provided with knurled knobs at the left a hand end in the place of crahks, such as are applied to the pounds actuating shafts.

Each of the actuating shafts is provided with a locating disk 60 just outside the frame work at the left hand end of the machine. Each of these disks has a notch or depression into which the tooth 61 of the associated detent lever 62 drops when the actuating shaft is in its normal posit-ion. The normal position of the actuating shaft is, of course, that in which none of the teeth of the actuating wheels is in mesh with any of the driving gears. The light spring 63 tends to draw the tooth of the lever into the notch of the locating disk so that the op erator will find it easy to give the actuating 46 shaft a full revolution,neither more nor 188$ If now the operator desires to translate eleven pounds, two shillings and two pence into United States money, he first grasps 50 the crank of the tens of pounds actuating shaft and turns this shaft through one complete revolution in the direction of the arrow shown ,in Fig. 2. A slight pressure on the crank is sufficient to disengage the tooth of the locating lever and permit the free rotation of the shaft. The detent tooth will, however, drop into the notch upon the completion of a single revolution, so that the operatorwill have no difliculty in stopping the rotation at the proper point. The operator next turns the crank of the units of pounds actuating. shaft one full revolution in the direction of the arrow shown in conjunction with this actuating crank.

Next theshillingsactuating shaft-is turned rotation of the carrying pinions affect the .zero position.

through two complete revolutions. The clicking of the detent mechanism aids the operator in counting the number of revolutions. j Next the pence actuating shaft is turned through two complete revolutions. The operation and results may be tabulated as follows:

The result of the multiplication is, of course, read through the window W from .the numeral wheels.

5 If, as is likely to be the case, the operator next desires to make. another translation of some other amount expressed in pounds sterling, it will be necessary to return the nu-- meral wheels to their zero position in order that the result may be read directly without the necessity of subtracti from the final resultthe amount indicate by" the nu meral wheels at the commencement of the translation. My invention provides means for returning the numeral wheels to their It will be noted in all of the sectional views that the shaft 20 upon which the numeral wheels" are loosely mounted is provided with a ratchet-like depression 65. Each of the numeral wheels is provided with a pivoted pawl 66, and a spring 67, which exerts a pressure upon the pawl. The numeral wheels are free to be advanced in the direction of the arrows applied to them without interference by the pawl and ratchet mechanism. Rotation in 'the direction of th arrows, only, is required in making 'the translations for which the machine is primarily intended. After the completion of a calculation the numeral wheels will be left in various angular positions with respect to the zero position. Thus when the reading of the register'is $48665 the first numeral wheel IE will be in its zero position, the other numeral wheels will be respectively in their fourth, eighth, sixth, sixth and fifth positions. 7 If, now, it is desired to returnall of the numeral wheels to zero, the numeral wheel shaft. 20 is given one complete revolution in the direction of the arrow shown in association with the numeral wheel shaft in Fig. 2, the resetting knob 69, being provided for this purpose. As the numeral wheel shaft is rotated the ratchet-like depression will engage the pawl of the first numeral wheel E, and causeit to rotate a full revolution with the numeral wheel shaft until the shaft returns to its normal zero position as determined by the locailng .lisk 67 and the detent lever 68. When the numeral wheel shaft has been retated through an angle equal to four spaces on the numeral wheels, the ratchet tooth will engage the pawl of the second numeral wheel 0, whereupon the rotation of this nnme'al wheel will be continued until the numeral wheel shaft has reached its zero position. So in like manner the continued rotation of the shaft will pick up in turn the numeral wheels T, M and G, and D, thereupon carrying all of them with the numeral wheel shaft into the normal zero position. The position of the pawls on the numeral wheels is, of course, such that when, after a complete revolution, the numeral wheel shaft is returned to its normal position, the zero positions of all of the numeral whecls will be in alinement with the window \V. After such resetting of the register to its zero position another calculation can be performed in the manner previously described.

It'will be manifest that l have described in detail only a single embodiment of my invention, which may be modified as may be required for a large number of specific pur poses. I do not wish, therefore, to limit myself to the precise details of construction herein set forth.
